Don't know how you arrived at the 29th but that is today. I'm a terrible cynic and I didn't think they would take this long. As I said earlier, I think AGO should be downgraded but only as part of the downgrade of municipal debt across the nation. To downgrade one and not the other doesn't make much sense to me.
I'm guessing they are trying to listen and address all of the points that AGO is raising. AGO does have a much better track record than Moody's, puts its own money on the line and is being downgraded by a firm such as this? The Moody's folks aren't idiots and don't want AGO to issue a press release saying how they have errors in their models and in their analyses.
Moody's has to put AGO into a position where all they can say is that it is a difference in opinion. Unfortunately, that is almost certainly how things will work out.
Moody's is in an interesting position. I don't honestly think AGO can stand behind widespread problems in the MUNI market but if they downgrade AGO, I would say they should downgrade a whole slew of municipalities.
